To all whom it may concern:

Be it known that I, FRANK D. WARD, a citizen of the United States, and aresident of the city, county, and State of New York,

5 (whose post-office address is 17 Battery Place, New York city,) havemade a new and useful Improvement in Machlnes for Rolling Rings, ofwhich the following is a description in such full, clear, and exactterms as will enable any person skilled in the art to which it pertainsto make and use the same.

According to my invention a ring of cast or otherwise formed ductile ormalleable metal is subjected to an operation which simultaneouslycompresses or compacts the metal of the ring and elongates or draws outthe metal, thereby enlarging the ring and producing a product which isvery tough, compact and even in its texture. These rings are useful innumerous situations notably as packing rings for projectiles. h

Referring to the accompanying drawings: Figure 1 is a side elevation ofthe'machlne; Fig. 2 is a plan view of the same; Flg. 3 is a right handend elevation (referring to Fig. 2.) Figs. 4 and 5 are elevational viewsof the rocking frame and its operating lever; Fig. 6 is across-sectional elevation of the machine showing the forming'rolls andthe work guide; and Fig. 7 is an enlarged elevation with parts brokenaway showing the forming rolls and their mounting devices together .withthe work' ring or work piece.

The work ring (indicated by the letter a in Fig. 7) is acted on by andbetween two rolls 10 and 11, the latter -having side flanges 12 betweenwhich the formerroll enters. The precise shape of the rolls varies ofcourse, with the form of the work being produced and one of the rolls isarranged to move laterally of its axis to and from the other roll topermit the introduction and removal of the work after which thelaterally or transversely movable roll is drawn back into activeposition and both of the rolls are then rotated with the work ringbetween them. The result of-this operation is that the metal of the ringis drawn down or elongated and the ring simultaneously enlarged. Thisresults in toughening or compacting the texture of the copper or othermetal. and a corresponding enlargement of the ring circumferentially.

The rolls 19 and 11 are carried on stubshafts 14 and 15 which aretapered into the ends of heavy journals 16 by which the stubshafts anddrawing rolls are mounted. The stub-shafts are rigidlyheld in thejournals 16 by tie-bolts 17 extending axially through the ].Ol1II1 2LlSand furnished with nuts or other fastenings on the outer ends thereof.The right hand journal 16 is rotatably mounted 1n bearings 18 in theframe of the machine and its axial position is adjustably maintained bya guide 19 running in. annular groove 20 in the journal between .thebearings 18. This guide plate 19 is held rlgidly yet ad ustably betweenthe hearings or boxes 18 by means of a screw shaft 21 fitted in theframe and furnished with' adjusted and fastened. The outer end of theright hand journal 16 has fixed to it a spur gear 22 which meshes withthe pinion 23 on a rotary shaft 24 mounted in the frame and adapted. tobe driven in any desired manner from a motor or any other source ofpower.

The second or left hand journal 16 is rotatably mounted in boxes 25formed in a secondary frame 26. The secondary frame extends transverselyof the main frame and is mounted to rock around a shaft 27 carriedlongitudinally in the main frame parallel with the shaft 24. The boxes25 are furnished withr a guide plate 19 and adjusting screw 21 the sameas before described which cooperate with the left hand journal 16 alsoas before described. The left hand journal 16 carries a spur gear 28which is in mesh with a pinion 29 fastened to the shaft 27. Theshaft 27is journaled in the main frame and extends to the right hand end of themachine where it is furnished with a pinion 28 in mesh with the spurgear 29 on the shaft 24. Thereby the shafts 24 and 27 are caused to'rotate in unison and in such a I manner that the two journals 16 aredriven in opposite directions not-withstanding that the secondary frame26 may be simultaneously swinging around the center of the shaft 27.

c. by manual operation, lifted. The arm 33, engaging the locking wall orshoulder 34 as shown in Fig. 4, prevents the toggle 31 from breakinginto the position shown in Fig. 5 unless the arm 33 is lifted clear ofthe shoulder 34 and this lifting must be done manually and cannot bedone accidentally. This lifting of the arm 33 results in thrustingbackward the link 32 and breaking the toggle 31 which results inswinging down the front end of the secondary frame 26 and moving theroll 11 transversely of its axis away from the roll 10 so as to allowthe introduction and removal of the work. It will be further noted thatthe arm 33 is articulated by a link 34 (see Figs. 4 and 5) to thelocking wall or shoulder 34 which constrains or confines the movement ofthe arm and further forms with the arm a second toggle operating withthe first toggle formed by the links 31. Therefore the frame 26 iscontrolled by two toggles, 11. e. a main toggle 31 and an operatingtoggle composed of the lin rs 32 and 34 which latter or operating toggleis thrown back and forth by the hand lever 33.

On the main frame of the machine at the station occupied by the rollsl0. and 11 is a work gage comprising a stationary part 35 furnished withlugs 36 to attach it to the frame and a swinging or opening part 37connected to the part 35 at its bottom by hinge 38 and having a lug 39at its top loosely received in a guide 35 on the section 35.

40 is a hand cam to lock the lug 39 and the section 37 rigid with thesection 35, but which when released allows the section 37 to drop backslightly for the introduction and removal of the work. The gage 3537embraces the rolls l0 and 11 as shown but the part of the guide whichembraces the roll 11 is much larger than the roll and is in fact of aninternal diameter (when the cam 40 is locked) equal to the designed extcrnal diameter of the work ring when finished. Therefore in theoperation of the machine when the work is in place between the rolls 10and 11 the rolls are operated to draw and enlarge the ring and thisoperation is continued until the ring is enlarged to the internaldiameter of the work gage 35-37 when the same is closed. \Vhen the ringis thus enlarged the operation is completed, the rotation of the diesmay or may not be stopped, the guide segment 37 is allowed to fall backand the arm 33 is thrown up which separates the rolls 10 and 11 and thefinished ring may be readily removed. A new ring is then inserted; theguide segment 37 is moved back, the cam 40 locked and the arm 33 isthrown down to restore the toggle 31 and return the rolls 10 and 11 tooperation.

The process and product described herein is made the subject of theclaims in my copending application, filed June 22, 1915, Serial No.35526 entitled Process and product of making rings.

Having thus described my' invention, what I claim as new and desire tosecure by Letters Patent of the United States is 1. In a machine forrolling rings, the

combination of opposing rollers adapted to roll the ring between them toextend the ring and a continuous curved Work gage encircling the ringand serving to limit the extension thereof.

2. In a machine for rolling rings, the combination of opposing rollersadapted to roll the ring between them to extend the ring and acontinuous curved work gage encircling the ring and sewing to limit theextension thereof, said work gage having a movable part which may bethrown back to release the work.

3. In a machine for rolling rings, the combination of opposing rollersadapted to roll the ring between them to extend the ring and acontinuous curved work gage encircling the ring and serving to limit theextension thereof, said work gage having a section adapted to drop awayor move laterally from the work to release the same.

4. In a machine for rolling rings, the combination of opposing rollersadapted to roll the ring between them to extend the ring and acontinuous work gage encircling the ring and serving to limit theextension thereof, said work gage having a section adapted to move toand from the work for .the purpose specified and a cam latch toreleasably hold the movable section in place.

5. In' a. machine for rolling rings the combination of opposing rollsadapted to roll the ring between'them, both rolls mounted on drivenshafts which extend in opposite directions respectively from the rollsand means for carrying one shaft to move laterally bodily toward andfrom the other whereby the rolls mav be squarely engaged and disengaged.

6. In a machine for rolling rings the combination of opposing rollsadapted to roll the ring between them, both rolls mounted on drivenshafts which extend in opposite directions respectively from the rolls,means for carrying one shaft to move laterally bodily toward and fromthe other whereby the rolls may be squarely engaged and disfor rockingit, a second rotary shaft carried in the rocking frame so that thesecond shaft has a planetary motion around the first shaft, means forrotating the shafts irrespective of the said planetary motion androllers mounted on the shafts to roll the ring between them.

8. In a machine for rolling rings the combination of opposing rolls toroll the ring between them, a rotary shaft mounted in fixed bearingscarrying one roller, a rocking frame, a rotary shaft mounted therein andcarrying the other roller, a toggle conmeeting the rocking frame with astationary part of the machine and a. hand lever including a secondtoggle for making and breaking the first toggle.

9. In a rolling machine or mill the combination with the opposing rolls,of tapered arbors to carry them, shafts with recessed ends in which thearbors are fitted and screws mounted longitudinally in the shafts andengaging the arbors relnovably to hold them in place.
